Hypertonic Expansion of the Extracellular Fluids

Abstract: Summary 1. Sodium chloride was added to the milk given to premature infants and newborn piglets which were then reared by hand. 2. The addition of salt led to (a) an abnormal increase of weight; (b) a rise in the serum sodium and chloride; (c) an expansion of the extracellular volume and ultimately massive oedema; (d) a reduction in the catabolism of tissue protein; (e) no increased excretion of potassium, if anything the reverse. 3. Similar and. even more clear cut results were obtained when the piglets were … Show more

“…In the rat and in the dog saline infusion has been shown to increase filtration rate in superficial nephrons and increase fractional sodium excretion [1,23,53]. In studies in neonates [35], human infants and piglets fed salted milk and water devel-oped edema, and sodium and chloride concentrations in serum increased. When salt was then restricted, weight loss occurred accompanied by a decrease in sodium concentrations.…”

“…The kidneys of new-born animals do not respond as well as those of the adult to Na load (McCance and Widdowson, 1957; Aperia, Broberger, Thodenius & Zetterstrom, 1972;Kleinman & Reuter, 1974). However, due to difficulty in obtaining a new-born model, studies on the renin-aldosterone system and its response to chronic Na+ depletion and volume contraction are scarce.…”

“…This contained more sodium, chloride and potassium than sow's milk, and piglets having it developed hypertonic expansion of the extracellular fluids. This was more fully investigated by McCance & Widdowson (1957), and it was then shown that human infants reacted in a very similar way. The animals in the first experiments also retained more potassium from the cow's milk mixture than they appeared to require for co-ordinated growth.…”

“…had been added. This contained the same concentration of chloride as the 0 7 % NaCI solution used in the previous experiments (McCance & Widdowson, 1957). The third piglet was given a volume of sow's milk times as great as the volume of water.…”
